Just ordered canvas :wings:
I'll be ordering steel end of next week, axle shortly thereafter.
Still on the fence on what the final suspension will be. Probably use my old mini truck leafs at first just to get it mobile, but at some point, plan on independent of some sort. It's one of those "not because I absolutely have to have it" things, but rather because I enjoy a challenge. Seriously considering a variant of the Track Trailer MC2 idea...

It seems like the dynamic camber changes could be an interesting problem. I do like the fact you maintain a nice open spot in the center of the trailer...at least more than trailing arms. The side-side forces are nicely transmitted to the lateral arm too. And most of all, I haven't seen any DIY folks give it a try so why not be the first. :victory:
